The Kimberley Diamond gets its name from the mine in South Africa where it was found sometime before 1868. It was cut from a 490-carat crystal. The champagne-colored, emerald-cut diamond will be on display through the end of June 2014. (AP Photo/American Museum of Natural History, Denis Finnin) less
